Legs buckle on me

Hi everyone can anyone please suggest what to do, I’m a type 2 diabetic which is under control but my legs just buckle on me without any reason which is worrying as I live on my own, I get a lot of cramp in my left leg and my ankle left foot gets really swollen, been to see my diabetic nurse but she’s saying it’s not related to my diabetes and told me to go bk to my doctor and see what he suggests, I’m 57, thanks for taking the time to read this

If your type2 is “under control” then pretty much have to guess. You say the foot is swollen, does the big toe especially really hurt? That would point to gout.

Try some multi-mineral supplements and some epsom salts baths. You could be low in minerals.

my GP recommended checking vit d level
